The Yaghan culture flourished for almost 8,000 years, and the coastal people, who number fewer than 2,000 today, influenced Charles Darwin’s thinking regarding the adaptability of humans to various environmental conditions. Their former lands are inscribed in a research and conservation program as part of the UNESCO Cape Horn Biosphere Reserve. Within the noncontiguous Cape Horn and Alberto de Agostini national parks that make up the reserve, glaciers are surrounded by evergreen forests and peat bogs, while Peale's and black dolphins and Magellanic and rockhopper penguins thrive.
